Calc 3 is the most powerful and elegant calculator in the market. Its functions are easy to use, its design is friendly for everyone and it is made to serve plenty of calculations in daily life. Additionally the feature-rich and powerful capabilities also make it ideal for scientists, engineers and students.

FEATURES:

- 3 WAYS OF INPUT: + Natural Expression or Formula (NAT): expressions are input in the natural order as written in the textbooks + Immediate Execution (IE): calculations are executed after each key press, similar to various popular calculators, such as: Windows system calculator, Mac system calculator, several basic models of Casio calculators, etc. + Reversed Polish Notation (RPN)
